Description

Technical Field

[0001] The invention belongs to the technical field of plant protection equipment, and in particular relates to an unmanned aerial vehicle (UAV) landing pad that is convenient for field installation. Background Art

[0002] Plant protection drones are unmanned aircraft used for agricultural and forestry plant protection operations. This type of drone consists of a flight platform (i.e. fixed-wing, helicopter, multi-axis aircraft), a navigation flight control, and a spraying mechanism. The spraying operation is achieved through ground remote control or navigation flight control, and can spray pesticides, seeds, powders, etc. Compared with general drones, this type of aircraft has a larger size and weight. People have found that during plant protection operations, it is easy to fail to achieve a smooth landing due to uneven ground, and it is also easy to find a suitable take-off and landing site in the field, which brings some inconvenience to plant protection operations.

[0003] For this reason, people have invented some helipads dedicated to drones, such as the patent with publication number CN207129165U, which is a portable drone helipad that can land and land drones on various terrains. However, it should be noted that the size of the three supporting legs of the helipad after unfolding is larger than the size of the parking platform, resulting in a large overall footprint. However, it is difficult to find a large place to place the helipad in many plant protection operations, so it is not suitable for the take-off and landing of plant protection drones. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a drone landing pad that is easy to install in the field. It is fixed to the ground by cuttings and is more suitable for fixation in outdoor conditions such as farmland.

[0005] In order to solve the problems of the prior art, the present invention discloses a drone landing pad that is convenient for field installation, comprising:

[0006] Ground fixings for insertion into the ground to achieve ground fixing,

[0007] A horizontal fixing member for supporting the lifting platform, wherein the horizontal fixing member is pivotally mounted on the top of the ground fixing member and is evenly distributed along the circumferential direction.

[0009] A supporting member is used to provide support for the horizontal fixing member, and the supporting member is installed on the ground fixing member.

[0010] Furthermore, it also includes:

[0011] The strip airbag is used for cushioning. When inflated, the strip airbag is clamped in the slot of the horizontal fixing member in the form of a spiral line, and an air nozzle is provided at the end thereof. After the strip airbag is inflated and fixed, it supports the landing platform and forms a certain distance between it and the horizontal fixing member.

[0012] Furthermore, the ground fixing piece has a pivot platform, a connecting shaft and a drill rod connected from top to bottom, the pivot platform has a plurality of pivot parts evenly distributed around the circumference, the pivot parts are connected to the pivot ends of the horizontal fixing piece in a one-to-one correspondence, the connecting shaft is threadedly connected to the support piece, and a tip is provided at the bottom of the drill rod.

[0013] Furthermore, the outer wall of the drill rod is provided with a plurality of anti-rotation ribs evenly distributed around the circumference, and the anti-rotation ribs are connected to the connecting shaft.

[0014] Furthermore, connecting holes A are provided at both ends of the outer edge of the sector plate, and connecting holes B are provided at the outer end of the horizontal fixing member. The connecting holes A of the sector plate are connected to the connecting holes B of the horizontal fixing member through connecting ropes.

[0015] Furthermore, the support member has a limit boss and a connecting portion connected from top to bottom, the connecting portion is threadedly connected to the connecting shaft, and the pivot end of the horizontal fixing member has a limit slot, and the limit slot is constrained by the limit boss to limit the downward movement of the horizontal fixing member.

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0033] like Figures 1 to 10 As shown, a drone landing pad that is easy to install in the field includes: a ground fixing part 1, a horizontal fixing part 3, a take-off and landing platform 6 and a support part 4.

[0034] The ground fixing piece 1 is a rod-shaped structure, which is used to be inserted into the ground to achieve ground fixing. Since it is a single-rod structure, it can be fixed under any terrain conditions, and the deeper it is inserted into the ground, the higher the firmness is, which effectively prevents tipping. Preferably, the length of the entire ground fixing piece 1 is 1-1.5m, and the effective insertion depth is not less than 1 / 2 of the length.

[0035] like Figure 7As shown, as a preferred example, the ground fixing member 1 has a pivoting platform 1.1, a connecting shaft 1.2 and a drill rod 1.3 connected integrally from top to bottom. The pivoting platform 1.1 has a thickness of 3-4 cm and a maximum diameter of 10-14 cm, and has eight pivoting parts 1.1a evenly distributed around the circumference. The connecting shaft 1.2 has a length of 8-12 cm and a width of 5-7 cm, and its outer circumferential surface is processed with external threads. The diameter of the drill rod 1.3 is 3-4 cm, and a tip 1.3c is provided at the bottom.

[0036] As a preferred example, the outer wall of the drill rod 1.3 is provided with a plurality of anti-rotation ribs 1.3b evenly distributed around the circumference, and the anti-rotation ribs 1.3b are connected to the connecting shaft 1.2. The function of the anti-rotation ribs 1.3b is to effectively prevent the entire apron from rotating after the ground fixing member 1 is inserted into the ground, and at the same time to improve the strength of the connection between the drill rod 1.3 and the connecting shaft 1.2, and play the role of a reinforcing rib.

[0037] The horizontal fixing member 3 is used to support the lifting platform 6. There are eight horizontal fixing members 3, and their pivot ends 3.1 are mounted one by one on the pivot part 1.1a of the ground fixing member 1 through the pivot shaft 5. In order to realize the vertical insertion of the ground fixing member 1 to ensure that the lifting platform 6 is in a horizontal state, a bubble level is arranged on the pivot platform 1.1.

[0038] The support member 4 is used to provide support for the horizontal fixing member 3 , and the support member 4 is installed on the ground fixing member 1 .

[0039] As a preferred example, Figure 6 As shown, the support member 4 has a limit boss 4.1 and a connecting portion 4.2 connected from top to bottom and a center hole that passes through the upper and lower end surfaces. The center hole of the connecting portion 4.2 is processed with an internal thread so as to be threadedly connected with the connecting shaft 1.2. The pivot end 3.1 of the horizontal fixing member 3 has a limit slot 3.4. The limit slot 3.4 is constrained by the limit boss 4.1 to limit the downward movement of the horizontal fixing member 3. That is to say, when the slot 3.4 of the horizontal fixing member 3 contacts the limit boss 4.1, the horizontal fixing member 3 is just in a horizontal state and will not continue to swing downward. When the support member 4 is removed, the horizontal fixing member 3 sags under the action of gravity, making the radial dimension smaller and more convenient for subsequent storage.

[0040] As a preferred example, a plurality of reinforcing ribs are provided on the outer circumferential surface of the connecting portion 4.2, and the reinforcing ribs are connected to the limiting boss 4.1.

[0041] The landing platform 6 is used for taking off and landing. The landing platform 6 includes eight sector plates 6.1 connected by connecting buckles 7 along the circumferential direction. Obviously, the landing platform 6 formed by assembling the sector plates 6.1 is a center of a circle or a circular ring. Fig. 9As shown, due to the assembly connection, the whole can be stored in a folded manner. The connecting buckle 7 is a buckle, which can be disassembled and overlapped to achieve the formation and release of the connection. It is an existing component, so it is not repeated. The fan-shaped plate 6.1 is connected to the horizontal fixing member 3 in a one-to-one correspondence. As a preferred example, the outer edges of the fan-shaped plate 6.1 are provided with connecting holes A6.1a at both ends, and the outer ends of the horizontal fixing member 3 are provided with connecting holes B3.3. The connecting hole A6.1a of the fan-shaped plate 6.1 is connected to the connecting hole B3.3 of the horizontal fixing member 3 through a connecting rope, so that the fixing of the lifting and landing platform 6 can be achieved.

[0042] Since the plant protection drone is heavier, it is necessary to consider the buffering of the landing moment when landing to avoid serious collision due to excessive speed. As a preferred example, the present invention also includes a strip-shaped airbag 2.

[0043] The horizontal fixing member 3 is provided with a plurality of slots 3.2. The strip airbag 2 is wound in the form of a spiral line and mounted in the slot 3.2 of the horizontal fixing member 3 in the inflated state. The end of the strip airbag 2 is provided with an air nozzle 2.1 for inflation and deflation. After the strip airbag 2 is inflated and fixed, it supports the take-off and landing platform 6 so that a certain interval is formed between it and the horizontal fixing member 3. The interval height is set to 2-4cm according to the diameter of the strip airbag 2 after inflation. The present invention adopts the strip airbag 2 as a buffer because the strip airbag 2 is more convenient to store than buffering means such as air cushions or soft cushions, such as Figure 8 As shown, the strip-shaped airbag 2 can be rolled up after being deflated, and has a smaller volume and is more convenient to store and carry. Compared with other elastic components, the structure is simpler, the number of components is smaller, and it is easier to install.

[0044] When the present invention is used, the support member 4 is first installed on the connecting shaft 1.2, so that the horizontal fixing member 3 is in a horizontal state. Then the drill rod 1.3 is inserted into the ground to a suitable depth. Then the inflated strip airbags 2 are coiled on the horizontal fixing member 3 in sequence, and finally the landing platform 6 is unfolded and placed on the strip airbags 2 and connected to the horizontal fixing member 3 to complete the fixing of the entire apron.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
